A four link rear suspension is used on all models. The axle housing is connected to the frame by two upper and two lower control arms with rubber pivot bushings at each end of the control arm. The control arms maintain the geometrical relationships of the rear axle with the frame, oppose torque reaction on acceleration and braking and provide for optimum handling characteristics.
Two coil springs support the weight of the car in the rear suspension. They are retained between seats in the frame and brackets welded to each axle housing tube. A rubber insulator is used to isolate the coil spring upper end from the frame seat and the lower end sits directly on the axle tube mounting bracket.
Sealed shock absorbers are mounted between a bracket welded to each axle housing tube and the upper spring seat, with the top inclined toward the center of the car. The shock absorbers are externally the same for all models, but vary in hydraulic control to provide a well-controlled but soft ride.
A steel stabilizer shaft is used to improve side roll stability on models with option F41. The one-piece shaft attaches to the lower control arms and is positioned directly under the rear axle housing. The shaft will support the weight of the car when a two-post axle engaging hoist is used for lifting.
Rubber bumpers are mounted near the outer ends of the axle housing and at the center of the frame cross-member to prevent metal-to-metal contact during compression travel or bottoming of the suspension.
